  <h2>Creating a DataReader</h2>

  <p>A DataReader is added to a Subscriber by default when a Subscriber
  is created. Additional DataReaders can be created by selecting a DataReader from the
  palette and adding it to the DataReader compartment of a
  Subscriber. QoS policies can be added to the DataReader as
  needed.</p><img alt="DataReader example" src=

  <p>The DataReader must be connected to a Topic, ContentFilteredTopic, or MultiTopic to be semantically complete.
  See <a href="../diagrams/connecting_figures.html">Connecting Figures</a>
  for information on how to connect a DataReader to a topic related figure.</p>
